As an example:

Please write me a cursor to iterate over this table with all necessary variables declared:

CREATE TABLE #TempContactIDs
(
ContactID INT
);

This saves SO much time for menial, repetitive cursor creation.  That query will result in the following:

DECLARE @CurrentContactID INT;

DECLARE ContactCursor CURSOR FOR 

SELECT ContactID FROM #TempContactIDs;

OPEN ContactCursor;

FETCH NEXT FROM ContactCursor INTO @CurrentContactID;

WHILE @@FETCH_STATUS = 0

BEGIN

    -- Here is where you can use @CurrentContactID to do whatever you need.

    -- This example just prints it.

    PRINT @CurrentContactID;

    FETCH NEXT FROM ContactCursor INTO @CurrentContactID;

END;

CLOSE ContactCursor;

DEALLOCATE ContactCursor;
